[0050] The temperature control component 3 also includes a placement tray 20, a sample tube 21, a right-angle plate 22 and a first extension plate 23. A placement tray 20 is arranged on the inner side of the insulation box 5. A plurality of placement holes are opened on the inner side of the placement tray 20. Sample tubes 21 are placed on the inner sides of the placement holes. Right-angle plates 22 are fixedly connected at both ends of the placement tray 20. The right-angle plates 22 are located above the first hollow plate 16. The bottom of the right-angle plates 22 are fixedly connected to the first extension plates 23, and the positions of the first extension plates 23 correspond to the first hollow plates 16. One of the first extension plates 23 extends to the inner side of one of the first hollow plates 16 and is threadedly connected to the second screw 18. Another first extension plate 23 extends to the inner side of another first hollow plate 16 and is slidably connected to the second fixed rod 19. The first extension plates 23 are slidably connected to the corresponding first hollow plates 16.

[0051] The temperature control component 3 also includes a temperature control sensing module 24 and a pressure sensing module 25. The temperature control sensing module 24 is fixedly connected to the top of the base 6, and the position of the temperature control sensing module 24 corresponds to the placement plate 20. Multiple pressure sensing modules 25 are fixedly connected to the top of the temperature control sensing module 24, and the positions of the pressure sensing modules 25 all correspond to the sample tubes 21.

[0052] The temperature control assembly 3 also includes a first linkage plate 26, a second hollow plate 27, a second extension plate 28 and a second linkage plate 29. Both ends of the first movable rod 14 close to the blocking door 8 are fixedly connected to the first linkage plate 26, and the bottom of the blocking door 8 close to the first linkage plate 26 is fixedly connected to the second hollow plate 27. The inner side of the second hollow plate 27 away from the blocking door 8 is slidably connected to the second extension plate 28. The second extension plate 28 is fixedly connected to the second linkage plate 29 on the side located outside the second hollow plate 27. The second linkage plate 29 is rotatably connected to the side of the first linkage plate 26 away from the first movable rod 14.

[0053] Specifically: the sample to be stored is placed inside the sample tube 21, and then the sample tube 21 is placed inside the heat preservation box 5 with a temperature corresponding to the sample to be stored;

[0054] By controlling the control host 1 to start the first motor 12 corresponding to the inner side of the heat preservation box 5 and drive the first screw 13 to rotate, the first movable rod 14 threadedly connected to the outer side of the first screw 13 can be driven to move on the inner side of the second movable groove to the side close to the blocking door 8. When the first movable rod 14 moves, the two first linkage plates 26 can be driven to move synchronously to the side close to the blocking door 8, so that the second linkage plate 29 can be squeezed and the blocking door 8 can be pushed. Through the rotational connection effect between the blocking door 8 and the rotating seat 7, when the side of the blocking door 8 away from the rotating seat 7 is pushed, the blocking door 8 can be flipped, so that the blocking door 8 can cancel the blocking effect on the opening of the heat preservation box 5.

[0055] During the flipping process of the blocking door 8, the second hollow plate 27, the second extension plate 28 and the second linkage plate 29 will gradually approach a state perpendicular to the first linkage plate 26. At this time, the distance between the second linkage plate 29 and the second hollow plate 27 can be adjusted by setting the second extension plate 28, so that adaptive adjustment can be made according to the flipping angle of the blocking door 8.

[0056] When the first movable rod 14 moves toward the side close to the blocking door 8, it can drive the second movable rods 15 at both ends to move synchronously toward the side close to the blocking door 8, thereby driving the first hollow plate 16 on the top of the second movable rod 15 to move synchronously, and through the connection setting of the first hollow plate 16, the top right-angle plate 22 and the first extension plate 23, the placement tray 20 is driven to move synchronously inside the heat preservation box 5 toward the side close to the blocking door 8. At the same time, through the extension setting of the second movable rod 15, the placement tray 20 can be moved out of the inside of the heat preservation box 5, so as to facilitate the placement of the sample tube 21 inside the placement hole inside the placement tray 20;

[0057] Then, by turning on the first motor 12 to drive the first screw 13 to rotate in the opposite direction, the placement plate 20 can be driven to move back to the inside of the insulation box 5, and the blocking door 8 is driven to block the opening side of the insulation box 5, and then the temperature inside the insulation box 5 is kept warm;

[0058] The temperature control sensing module 24 is configured as a temperature sensor, which can detect the temperature inside the heat preservation box 5. The pressure sensing module 25 is configured as a pressure sensor, which can detect the existence state of the sample tube 21. The temperature sensor and the pressure sensor are prior arts and will not be described in detail here.

[0059] After the placement tray 20 moves to the corresponding position on the top of the temperature control sensing module 24, the second motor 17 is turned on and the second screw 18 is driven to rotate, thereby driving the first extension plate 23 threadedly connected to the second screw 18 to move up and down inside the first hollow plate 16, so that the placement tray 20 can be driven to move up and down inside the insulation box 5 through the setting of the first extension plate 23 and the right-angle plate 22, thereby driving the sample tube 21 inside the placement tray 20 to move downward and contact the pressure sensing module 25, and at the same time, the electric push rod 9 can be turned on and the squeezing tray 10 can be driven to move downward, so that multiple sample tubes 21 can be squeezed, further increasing the contact force between the bottom of the sample tube 21 and the pressure sensing module 25, so that the pressure sensing module 25 can more clearly display the number of sample tubes 21 inside the placement tray 20.

[0060] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.

[0061] Embodiment 3:

[0062] This embodiment 3 is used to further disclose the specific structure of the convenient moving component 4 on the premise of the above embodiment. Through the coordination of the convenient moving component 4 and the structure in the above embodiment, it is achieved that the bottom of the sample preservation device can be conveniently moved and fixed, and the sample preservation device can be directly moved when it is necessary to move a small range, thereby improving the convenience of using the sample preservation device.

[0063] The sample storage device provided in Example 1 and Example 2 is further optimized. Specifically, Figure 8 As shown, the convenient moving component 4 includes a fixed recessed plate 30, a first baffle plate 31 and a third fixed rod 32. The fixed recessed plate 30 is fixedly connected to the middle of the outer side of the control host 1 and the placement cabinet 2, the bottoms of both ends of the control host 1 and the placement cabinet 2 are fixedly connected to the first baffle plate 31, both sides of the top of the first baffle plate 31 are fixedly connected to the third fixed rod 32, and the top of the third fixed rod 32 is fixedly connected to the fixed recessed plate 30.

The second baffle 33 is fixedly connected to the bottom of the cabinet 2 away from the blocking door 8, and the third motor 34 is fixedly connected to the top of the fixed recessed plate 30 close to the second baffle 33. The output end of the bottom of the third motor 34 extends to the bottom of the fixed recessed plate 30 and is fixedly connected to the third screw 35, and the bottom of the third screw 35 is rotatably connected to the top of the second baffle 33.

[0065] The convenient moving component 4 also includes a movable concave plate 36 and a universal wheel 37. The movable concave plate 36 is arranged below the outer side of the control host 1 and the placement cabinet 2, and one side of the movable concave plate 36 is threadedly connected to the third screw rod 35, and both ends of the movable concave plate 36 are slidably connected to each of the two third fixed rods 32. The bottom of both ends of the movable concave plate 36 is fixedly connected to two universal wheels 37, and each of the two universal wheels 37 wraps each first baffle 31.

[0066] Specifically: when the control host 1 and the placement cabinet 2 need to be moved, by turning on the third motor 34 and driving the third screw 35 to rotate, the movable recessed plate 36 threadedly connected to the third screw 35 can be driven to move up and down outside the control host 1 and the placement cabinet 2. At the same time, through the setting of the third fixed rod 32, the up and down movement of the movable recessed plate 36 can be stabilized, so that the universal wheels 37 at the bottom of both ends can be driven by the movable recessed plate 36 to move downward synchronously and contact the ground. The support setting of the universal wheels 37 for the control host 1 and the placement cabinet 2 can improve the convenience of the control host 1 and the placement cabinet 2 in a small range.

[0067] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
